CLAMP.

.Application led December 26, 1923. Serial No. 682,733.

T0 all whom. t may concern.

Be it known that I, HOWARD H. Davis, a citizen of the United States, residing at, East Columbus, in the county of Franklin and State of Ohio, have invented new-and useful Improvements in Clamps, of which the following is a specification.

lThis invention relates to a pipe clamp `mainly designed for railroad car construction, the general object of the invention ber' ing to provide wedge means for wedging a.

.a-'vlded w1th lugs 9 at the slde edges for enpipe in a hole in a supporting member.

This invention also consists in certain other features of construction and 1n the combination and arrangement of the several parts, to be hereinafter fully described, illustrated in the accompanying drawings and specifically pointed out in the appended claims.

In describing my invention in detail, reference will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the sev-v eral views, and in which Figure 1 is an elevation form of the invention.

Figure 2 is a sectionon line 2 2 ure 1.

Figure 3 is an elevation of another form.

Figure 4 is a section on line 4-4 of Figure 3.

Figure 5 is an elevation of another modilicationl Figure 6 is a ure 5.

Figure 7 is an elevation of a further form.

Figure 8 is a section on line 8-8 of Figure 7 Figure 9 is an elevation of another form.

Figure 10 is a section on line 10-10 of Figure 11 is a view of still another form.

Figure 12 is a section on line 12-12 of Figure' 11.

In all these figures the supporting plate is shown at 1, the pipe at 2 and the hole in the plate, through which the pipe passes, at 3. In the rst -form of the invention a plate 4 havin a curved wedge-shaped tongue 5 thereon' 1s bolted to the plate 1 by the bent extremities of a VU'"nolt 6 which has its bight encircling the. pipe. v The wedge-shaped tongue gngages that part of the pipe which is oppos1te the b/ight so as to wedge the pipe between the bight of the, U'b0lt and the showing `one Isection on line G--G of Figof Figtion are used instead of the U-bolt.' These plates are shown at 4 and are bolted to the plate 1 by the bolts 8. The plates are progaging the bolt heads for preventing turning movement of the bolts when the nuts are being tightened. The tongues 5 of these plates 4 engage the upper and lower parts of the pipe so that* the pipe is wedged between the tongues and is thus firmly connected with the plate 1.

In the form shown in Figure 5 and 6 the upper plate is made similar to the plates shown in Figures 3 and 4 but the lower plate is of much smaller dimensions, as shown at 4 so /that but a single bolt 8 is necessa to hold it in place. plate is similar to the plates above described. In the form shown in Figures 7 and 8 the upper plate is made as before described but the lower member 10 is of U-shape so that it will straddle the plate l with its bight r11 curved to conform to the lower wall of the hole 3. This member acts as a filler so that the tongue of the u per plate can wedge the pipe between itself and said filler member.

In the form shown in Figures 9 and 10 two small plates 12 are used for clamping the pipe to the plate 1,"these plates being similar to the plate 4 shown in Figures 5 and 6.

In the form shown in Figures 11 and 12 a small plate 12 and a filler member 10 are used to hold the 'pipe in place. The plate 12 is similar to the small plates before described and the filler member is similar to that shown in Figures 7 and 8. In all the forms the bolt, holes for the bolts which hold the wedge-shaped members in place are made larger than the bolts so that said members can have a oertainvamount of play to permit their tongues to act as wedges when the parts are to be assembled.

From the foregoing it will be seen that I have provided a pipe clamp which is very simple so that it is easy to apply and can In other respects thls be manufactured at small" cost. It is also very effective and will securely hold a pipe in a hole in` a supporting member.

It isltliought 'from the foregoing description that the advantages and novel features of my invention will be readily apparent.

I desire it to be understood that I may make changes in the construction and in the combination and arrangement of the several parts, provided that Such changes `fall within the scope of the appended claims.

vWhat I claim is:-

1. A pipe clamp of the class described for holding a pipe in an openingy in a supporting member comprising a plate having a wedge-shaped tongue extending at right angles therefrom and curved toen age the pipe and a portion oi the Wall of t e opening, a bolt for holding the plate to the su p'orting member and a projection 011 t e 20 plate for preventing turning movement of the bolt when its nut is ti htened.

2. A pipe clamp of the c ass described for holding a pipe in an opening in a supporting member comprising a plate having a Wedge-shaped tongue extending at right angles therefrom and curved to en age the pipe and a portion of the wall of t e opcnigg, a. bolt for fastening the plate to the supporting member and a. member having a curved part against which the pipe is pressed by the tongue when the parts are assembled.

In testimony whereofl I afiix my signature.

HOWARD H. DAVIS.
